PMU(Phasor Measurement Unit)을 활용한 제주계통 동기위상 측정에 관한 연구

It's difficult to monitoring of power system's security. And it's more difficult to monitoring precisely which like domestic power system with large capacity and complex utilities. The government project, which wide area power system monitoring with synchro-phasor measurement in Jeju-island's power system which is independent from main land's large power system, started in 2005 is the installation and operation of PMU devices on 154kV substations and HVDC convert station. In this paper present the strategy of Smart Power Grid by the result of a installation and test operation the PMU in Jeju power system.
